We demonstrate the imaging capability of a frequency modulated continuous wave (FMCW) lidar based on a fiber bundle. The lidar constructs velocity and range images for hard targets at a rate of 60 Hz. The sensing range is up to 30 m with 20 mW output power. The instrument employs custom electronics with seven parallel heterodyne receivers. An examp...

The unusual dynamics of the Venus atmosphere remains one of the most intriguing puzzles of our sister planet. IVOLGA (an Oriole bird in Russian and an abbreviation to “Fiber Infrared Heterodyne Analyzer”) will be the first-ever spaceborne instrument to measure transmittance spectra of Venus atmosphere with an ultra-high spectral resolution (≥ 1 000...

Accurate knowledge about the properties of the atmosphere of Mars is highly demanded in its climate simulation. To contribute to the Martian atmosphere investigation , authors propose the concept of a multichannel laser heterodyne spectroradiometer (MLHS) based on a CubeSat formfactor. The instrument will measure: mixing ratio of CO2, H2O, their ve...

This thesis is dedicated to the analysis, testing, and development of methods for imaging velocimetry and range finding based on multi-channel frequency-modulated continuous wave (FMCW) lidar in the near-infrared range. The study aims to develop a frequency-modulated lidar for creating low-pixel count imaging systems based on it. The work includes...

We present the project of a 2U CubeSat format spaceborne multichannel laser heterodyne spectroradiometer (MLHS) for studies of the Earth's atmosphere upper layers in the near-infrared (NIR) spectral range (1258, 1528, and 1640 nm). A spaceborne MLHS operating in the solar occultation mode onboard CubeSat platform, is capable of simultaneous vertica...

We present a concept of the Martian multichannel diode laser spectrometer (M-DLS) instrument, a part of the science payload onboard Kazachok landing platform in the framework of the ExoMars mission second stage. The instrument, a laser spectrometer operating in the mid-IR spectral range, is aimed at long-term monitoring of isotopic ratios in main M...

This work presents a laser heterodyne spectroradiometer and fundamentals of its design. The high spectral resolution spectroradiometer (λ/δλ ~ 10^7-10^8) is used for measurements of atmospheric СО2 and СН4 concentration and allows analyzing a fully resolved contour of individual rotational lines of vibrational spectra. This work is focused on a mul...

An application of tunable diode laser absorption spectroscopy (TDLAS) in combination with integrated cavity output spectroscopy (ICOS) was proposed for Martian atmosphere study, and has been implemented as a Martian multichannel diode laser spectrometer, or M-DLS instrument. Before its scheduled delivery to the ExoMars-2022 Landing Platform, the M-...

This work presents the design of multichannel heterodyne signal detection. The measuring capabilities of the proposed configuration were tested based on the developed multichannel laser heterodyne spectroradiometer (MLHS). The MLHS can simultaneously detect absorption features of atmospheric CO2 and CH4 in the NIR spectral range with an ultra-high...

We propose a new technique of remote wind measurements based on Doppler analysis of a CO2 absorption line in the 1.605 µm overtone band measured in the direct Sun observation geometry. Heterodyne spectroradiometric measurements of the solar radiation passing through the atmosphere provide an unprecedented spectral resolution up to λ/δλ∼6×107, with...

We consider the application of the heterodyne signal det­ection technique to measure the atmospheric transmission spectrum in the near­IR range, which makes it possible to measure for the first time the contour of a separate line of the vibrational – rota­tional CO2 band on the solar observation path with a high spectral resolution of l/ dl = 108....
